'PAPER OR FILE HOLDER.

SPECIFICATION forming part of Letters Patent No. 358,240, dated February 22I 1887. Application tiled June 18, 1886. Serial No. 205.553. (No model.)

.To all whom, it may concern.-

Bejit known that I, EDMUND W. WOOD- RUFF, ofWashington, inthe District ofOolunibia, have invented new and useful Improvementsin File or Paper Holders; and I do hereby declare that the following is a full and accu- -rate description of the same.

This invention relates to that class of leholders wherein the receptacle is constituted by a base-board and end board and two side boards, within which the papers are clamped by an adjustable file-board attached to the base-board by a clamping device which slides in an undercut-groove along the median part of said base-board5 and it consists, first, in au improved construction of the groove plate wherein the clamp slides, and, second, in improved means for attaching metallic sides to the base and head boards.

As to the rst part of my invention, the object is to substitute wrought-iron for cast-iron, and more firmly attach said plate to the baseboard than heretofore.

As 'to the second part of my invention, the object is to construct the sides with metal rods, instead of wood or metal plates, as heretofore.

A- further part of my invention has for its object the protection of the wooden front board from tire; and it consists in a metallic covering for said front board. 4

In the accompanying drawings, Figure l is a perspective view of my invention. Fig. 2 is a perspective view of my grooveplate detached. Fig. 3 shows a modification of the same. Fig. 4 shows in perspective the side rods detached. Fig. 5 is a transverse section of the base-board, showing the grooves for the Fig. 6 is a similar transverse section, showing the groove-platein position. Fig. 6 shows suggestions of changes in the crosssection form of the groove-plate. Fig. 7 is a perspective view showing the mode of applying the metallic cover to the front board. Fig. 8 is a perspective view of my tile-holder with a modified structure. Fig. 9 is a perspective view of the groove-plate for the same. Fig. l() is a vertical longitudinal section showing mode of attaching the side rods to the groove-plate cross-bar. Fig. 1l is a perspective view of the front board, showing modification in the mode of securing the side rods to said front board. Fig. 12 is a transverse section of the front board, showing mode of attaching and securing the front board and side rods by means of the metallic cover. Fig. 13 isa plan, partly in section, of the rear end of the base-board, showing how the ends of the are cut with a saw, and are only sufcient to receive the thick ness of the plate from which the groove-plate is made. Said groove-plate is composed of two strips, ff, each bent transversely along its median line at an angle of forty-five degrees, or thereabout, so that when one edge is inserted in the groove e the other edge will project in a plane coincident with the surface of the base-board, as shownin Fig. 6. The strips ff are at one end riveted or otherwise secured to a block, g, which tits and slides in the groove d when thc platesff are being inserted.

The side rods, H, for opposite sides of the holder I prefer to make from a single con tinuous piece of suitable wire, though I do not desire to conflne myself to cylindrical rods, because dat strips or plates may be substituted. The portions t' are adapted to rest in a groove, j, cut transversely in the end of the base-board, and the end portions, 7c k, enter the front board, B, either into holes boredinthe edges or into grooves l cut across the front board, to be retainedthere by a covering of some kind applied after the rods are in place; or the portion i may rest in the groove l cut transversely across the front board, and the end portions, lc k, may be conned in groove j. Figs. 4, 7, and 13 illustrate these arrangements, which are regarded as equivalents and matters for preference merely. In either case the lowermost rod II will pass into the deeper part of groove j and the uppermost rod H will rest in said groove outside said lowermost rod. This arrangement is shown in Figs. l and 13. To secure in place the parts in the groove j, the

ends iz of the plates ff may be extended and turned down so as to hook over and inclose said parts, or the ends of said plates f may be riveted or otherwise secured to a cross-bar, p, which will then rest in and fill the groove 7' in front of the rods i. VBy these means the sides of the holder are made of rods continuous from side to side, and therefore not only less costly, because no labor is required to join them, but also much stronger, because they are continuous and without joints.

For security against fire it is desirable to cover the front of' the front board, B, with aplate of metal, Q, and I have attached the same eciently and cheaply, as shown in Fig. 7, by cutting a groove, r, in each edge of the front board and bending the corresponding edges of In practice said plates are bent so as to be a very litu tle narrower than the front board, and are put in place by sliding on from the end, so that a tight fit is easily attained and slight shrinking of the board will not loosen the plate, because its resiliency will cause it to follow the wood as it shrinks. The edges of the plate Q turned into the wood, as described, will cover and confine the ends l.: 7; ofthe side rods, HH.

The extremities of the parts 1r Ir may be expanded laterally by flattening, as shown in Fig. 4, and said expanded ends, when embedded in the wood, will tend to prevent a withdrawal of said parts k from their beds.

A modification of the structure above described, preferable forsonie purposes, is shown in Figs. S, 9, l0, 11,12. The cross-harp isprovided at its ends with blocks s, perforated to receive the ends of the side rods, H, which then do not extend across the base-board, but terminate at the blocks s, to which they are rigidly riveted or otherwise secured.

The rods H, with their ends riveted to the blocks s at the extremities of the cross-bar p, may pass around the front of the front board, B, in the grooves I, or they may terminate in plates t, which in turn are secured to said front board. In that case the ends of said rods are riveted or otherwise secured to said plates; or the ends of said rods may pass through said front board and be riveted in the margin of the card-plate U, as shown in Fig. 11.

Having described my invention, I claim as new`- l. In a. paper or file holder, a groove-plate for the sliding clamp, constructed of strips f f with their outer margins bent downward to adapt them to enter and be embedded in the material of the base-board,substantially as set forth.

2. The base-board A of a file-holder, provided with the groove d through its center and the marginal undercut grooves e e, combined with a grooveplatc the margins whereof are adapted to enter said undercut grooves, substantially as described, to embed and hold said plate in the substance of said baseboard.

3. The base-board A of a file-holder, provided with the central groove, d, and the undercnt grooves c c, and with the groove j transversely across the end of said board, substanti ally as described com bined with a grooveplate composed of stripsff, the outer margins whereof are bent down to enter the undercut portions of said groove, for the purpose set forth, said strips being rigidly attached at one end to the block g, and at the other end fashioned to close over said groove 7' Wholly or in part, substantially as set forth.

4. In a paper or file holder, in combination with the base-board A and head-board B, the side rods, H, made continuous from side to side, substantially as set forth.

5. The base-boardA and headboard B, prol vided with the transverse grooves 7' and Z, respectively, combined with the side rods, H, continuous from side to side and having the central parts, t', andthe terminal parts k, confined in the boards A B, respectively, substaih tially as described.

G. Thebaseboard A and front board, B, pro vided with transverse grooves, substantially as described, and side rods, H, conti nuous, as described, combined with a groove-plate the front ond whereof covers and closes the transverse groovej, and confines therein the transverse portion of said side rod, substantially as set forth.

7. Ina paper or file holder, the front and base boards, A B, and the continuousside rods, H, combined with a metallic covering-plate the edges whereof cover and confine the transverse parts of said side rods, H, substantially as set forth.
